Before you go bungee jumping, make sure you've taken everything out of your pockets. Including your phone. Especially your phone.

It seems like such basic common sense that no one should need to be reminded about it — but as everyone knows, common sense isn't that common.

Hopefully Máirtín Farragher's misfortune will ensure none of us ever repeat his mistake: while leaping off Bloukrans Bridge in South Africa, the world's highest commercial bungee jump, his phone liberated itself from his pocket.

His scream of excitement quickly turns to a scream of despair as he realises what's happened.

The phone evidently had a pretty intriguing backstory, for a phone: on Facebook, Farragher wrote that the device was once lost in Italy "and the undercover police got it back and all that jazz".
